Abstract

Abstract Twenty-one derivatives of imidazolidine-2, 4-dione have been prepared by reactions of substituted amino acids with aryl isocyanates in aqueous medium. Pre-and post- emergent herbicidal activities of all the compounds have been tested, and stability of five derivatives has been followed in aqueous medium within the pH range from 7.6 to 13.0. The highest pre-emergent herbicidal activity has been found with the derivatives XI-XVI which ...
